On thing more: the IP addr you are ssh'ing from is reachable via Internet: $ telnet 137.222.187.241 22 Trying 137.222.187.241... Connected to mech-cluster241.men.bris.ac.uk. Escape character is '^]'. SSH-2.0-OpenSSH_6.1_hpn13v11 FreeBSD-20120901 If this is your intention (and not a fault) you should know what you are doing and have hardened the access, for example only RSA auth via SSH.
